MANUEL MEXDOZA, OF MADRID, SPAIN FLUISHAING APPARATUS FOR WATER-CLOSETS, LAVATQRIES,"aexff* Specification of Letters Patent.

Application filed July 22, 1904. Serial No. 217,711.

T 0 all whom it may concern:

Be it known that I, MANUEL subject of the King of Spain, residing at 100 Fuencarral, Madrid, in the Kingdom of Spain, architect, have invented certain new and useful Improvements in Flushing Apparatus for \Yater-Closets, Lavatories, and the Like, of which the following is a specification.

r apparatus for water-closets, lavatories, and

the like, and has for its object to provide an improved device which shall discharge the water with considerable force upon the actuation of a releasing device In order that my invention may. be readily understood and carried into effect, I will describe the same fully with reference to the accompanying drawings, in which Figure 1 is a vertical section through an apparatus constructed in accordance with my invention, and Fig. 2 is a section on line a a of same.

According to my invention I provide a vertical cylindrical box A, preferably of castiron, closed at its upper extremity by means of a cap B, fitted to same by means of a screw-joint. The vessel so formed has three separate orifices C, D, and E. v The first, C, gives entrance to the water from the main, while the two other orifices D and E are formed, respectively, in the bottom of the vessel and in the cap B. To the lower 0 ening D is screwed afitting F, provided Wit an operating-handle R, connected to a crank-arm carrying a vertical rod G and serving to produce the discharge of the water when shifted to the position shown in dotted lines. To the upper orifice E is fitted a tube H, communicating at itsupper end with the atmosphere. Thistube H, the length ofwhich varies with the impulsive force which it is desired to impart to the discharge, is closed at its free extremity by a ball-valve M, supported by guide-rods L, attached to the tube H.

The lower orifice D of the receptacle A is closed by another and larger ball-valve N, which thus obturates the delivery-outlet for the Water at the lower part of the vessel, which latter is also provided with a vertical rib 0, preferably cast inte ral therewith, said rib serving to prevent sturbance of the water by obviatin the formation of eddies and other abnormal movements which would otherwise tend to prejudicially affect the operation of the apparatus.

When the apparatus constructed as above Patented April 2,

.' described has been arranged in position and.

MENDozA, a

the parts occupy the position shown in Fig. 1, the handle R of the fitting F will remain depressed. owing to its own weight and that of the crank arm and rod G. the valve Yolk free communication between the vessel'and This invention has reference to flushing the outer air. Assuming'now thatv water begins to flow into the vessel A through the inlet C, the admission-cock of which is permanently open, the valve X, although a float, .not only will not float at this time, but, on

the contrary, owing to the pressure which commences to act only at its upper part, will close the outlet with gradually-increasingforce Upon the level of the water rising in the vessel A the valve M will rise and close the lower end of the tube H, cutting off the egress of'air. A portion of the air, which thusremains inclosed, will be compressed as the Water enters in inverse ratio to the pressure acting upon it, This pressure will be the piezometrio pressure of the distributing system where the installation is situated. A moment will arrive at which the water will cease to enter, when equilibrium is est ablished by the equalization of-the expansive force of the compressed air and the pressure exerted above it; In order to produce discharge of the Water contained under pressure in the vessel A, it is only necessary to move by hand theha-ndle B into the position shown in dotted lines, which in its displacement will operate the crank-arm and vertical rod G, lifting the valve N. When this latter leaves its seat, it will float to the surface.

The discharge-outlet having been freed in this manner, the water will be discharged with considerable force, owing to the action of the internal compressed air, which will act until as a result of the fall of the waterlevel the valve M reestablishes communication between the interior of the vessel A and the atmosphere. As the vessel empties the valve X will descend with the water. which .will not formeddies, owing to the presence of the rib O. hen the vessel is completely emptied, the valve X and all the other parts will return to their initial positions. whereupon the vessel will become recharged and ready for a further operation.

The arrangement shown in the accompanying drawings is given by way of example only, as the form of the apparatus may varyin many ways, not only as regards the 'turatingthe discharge-outlet for the watery 1 The other and smaller valve will "permit of! body of the casing or receptacle, but also as regards the nature and arrangement of theaccessory details, which although necessary for the operation of the device are not 5 concerned .in its principle or essential nature. For example, cases may arise in which, owing to the small pressure existing at the place at which the appliance is installed, it will not be necessary to provide for the discharge of any portion of the air con.

tained in the vessel, so that the valve M and the tube H may be dispensed with, the cover not being provided with any aperture. On

the other hand, in some cases the main pressure may be very great, so that it will be advisable to reduce the volume of compressed air, the valve M being arranged almost at the cover itself.

I claim- A flushing apparatus for water-closets, &c., comprising a casinghaving an inlet-tube depending within the same, an outlet,'and a lateral inlet and a vertical rib opposite'said lateral inlet, a valve closing said outlet, an independent valve closing the lower end of the air-inlet tube, and means for unseating the outlet-closing valve and allowing it to automatically reseat itself when the casing is emptied.

In testimony whereof I have hereunto set 0 my hand, in presence of two subscribing witnesses, this 5th day of J uly, 1904.
